I am trying to change my existing code for auditing drawings where I look for 2D items in 3D models. What I have found is that a lot of 2D object found are legitimate components because they make up part of a graphical group. So I want to exclude those entities in graphical groups and ONLY find 2d entities that are on their own (construction lines, etc.). If anyone has ever tried this, if you could help, it would be greatly appreciated!
